Introduction
The IC Card Prepaid Water Meters is a highly intelligent meter with
advanced microcomputer control technology as the core and
contactless smart card technology as the information transmission
method.
The meter is based on a rotary vane water meter and is equipped
with a new type of low-power, high-torque output,
pressure-loss-free motor control valve, a microcomputer controller
and a radio frequency card operation module.
The product performance complies with the national standard
GB/T778-2007 and the Ministry of Construction industry standard
CJ/T133-2007 and the drinking water and cold water meter safety
rules CJ266-2008, and can be used for the metering and charging of
water for residences, enterprises and institutions.
